Environmental Friendly Waterborne Industrial Color Paste - Non-Toxic Pigments for Industrial Use
Technical Superiority of Modern Aqueous Color Pastes
1. Ultra-High Coloring Efficiency
- Pigment load optimization:
- Achieves 95–98% pigment strength vs. conventional pastes (ISO 787-24/ISO 6504-3), enabling 15–30% dosage reduction.
- Nano-dispersed particles (D90 <1μm) maximize light scattering (Kubelka-Munk theory).
- Cost-saving metrics:
- Reduces colorant consumption by 1.2–1.8 kg per ton of base paint for mid-tone shades.
- 5% improvement in ΔE accuracy at 1/3 SD tinting levels (DIN 6175-2).
2. Precision Rheology Control
- Newtonian flow behavior:
- Brookfield viscosity: 800–1,200 cP @25°C (LVT spindle #3, 60 rpm).
- Thixotropic index: 1.0–1.2 (ASTM D2196) ensures anti-settling stability.
- Low-energy dispersion:
- Achieves Hegman 7+ fineness with 30% reduced mixing energy (400–600 rpm paddle agitation).
- Compatible with high-shear (Disperser) and low-shear (Planetary) systems.
3. Premium Pigment Selection
| Pigment Class | Weather Resistance | Lightfastness | Industry Benchmark |
|---|---|---|---|
| Organic Azo | 3–5 years (ISO 11341) | Class 6–7 (ISO 105-B02) | Clariant Hostaperm® Series |
| Phthalocyanine | 8–10+ years | Class 7–8 | BASF Heliogen® Grades |
| Inorganic Oxides | 15–20 years | Class 8 | Venator Altiris®/Tronox CR-8xx |
4. Comprehensive Color Space Coverage
- CIELab gamut:
- Covers 98% of NCS 1950 Atlas (ΔE<1.5 tolerance).
- Special effect pastes: Metallic (L* 25–90), Pearlescent (Interference 400–700nm).
- Smart tinting systems:
- 8–12 base pastes achieve 99% color match accuracy (Datacolor 800 spectrophotometer).
Professional Application Protocol
1. Pre-Use Compatibility Verification
- Stepwise testing procedure:
- Prepare 500g base paint sample (ISO 15528 sampling).
- Add 2% color paste incrementally under 400rpm stirring.
- Check for:
- Flocculation (Hegman gauge)
- Viscosity shift (Stormer KU viscometer)
- pH fluctuation (±0.5 tolerance)
- Troubleshooting matrix:
Issue Corrective Action Seediness Increase dispersant (0.2–0.5% BYK-190) Viscosity drop Add associative thickener (RM-8W, 0.1%) Color float Adjust surfactant HLB (12–14 optimal)
2. Optimal Dispersion Methodology
- Standard incorporation process:
- Pre-dilution: Mix paste:water = 1:1 (vol) for carbon black; 1:0.5 for oxides.
- Addition rate: ≤5% paste/min of total batch volume.
- Post-tinting mix: 20min @30–40°C (jacketed vessel preferred).
- Equipment guidelines:
Scale Mixer Type Tip Speed <500L Cowles blade 8–12 m/s 500–2,000L Sawtooth impeller 6–8 m/s >2,000L Helical ribbon 3–5 m/s
3. Storage & Handling Best Practices
- Preservation protocol:
- Temperature: 5–35°C (40°F–95°F).
- Container: UV-block HDPE drums with nitrogen blanket.
- Shelf life: 24 months (unopened), 6 months (opened).
- Freeze-thaw stability:
- Withstands 3 cycles (-10°C to 25°C) without rheology damage (ASTM D2243).
Critical Factors Impacting Color Paste Weather Resistance
1. Binder-Pigment Synergy
Emulsion selection criteria:
Resin Type PVC Range Weathering Performance Pure Acrylic 30–45% 10–15 years (Florida exposure) Styrene-Acrylic 35–50% 5–8 years Vinyl Acetate-Ethylene 40–55% 3–5 years Minimum film requirements:
- Exterior coatings: ≥30% emulsion content (ASTM D5324).
- Critical UV zones: 35–40% resin for TiO₂ extension.
2. Pigment/Extender Optimization
- Anatase TiO₂ prohibition:
- Rutile grade mandatory (≥98% purity, CI77891).
- Surface treatment: Alumina-silica-zirconia (ASZ) coating preferred.
- Filler restrictions:
Material Maximum Load Rationale Calcium Carbonate 15% Alkaline degradation risk Talc 10% Water sensitivity increase Kaolin 20% Chalking acceleration
3. Formulation Balancing Techniques
- Deep shade optimization:
- Reduce TiO₂ to 5–8% (vs. 18–25% in pastels).
- Increase UV absorbers (2–3% Tinuvin® 1130).
- Critical pigment parameters:
Color Depth PVC CPVC Adjustment Pastel (LRV >70) 35–45% +5% vs. standard Mid-tone (LRV 30–70) 28–35% ±0% Deep shade (LRV <30) 20–28% -8% to prevent mud cracking
4. Accelerated Weathering Correlations
- Testing equivalency:
Lab Test Real-World Equivalent Performance Threshold 2,000h QUV-B 5–7 years Midwest USA ΔE<3.0, Gloss retention >70% 1,500h Salt Spray 10 years coastal Blistering ≤6 (ASTM D714) 50 Thermal Cycles Arctic/tropical service Adhesion ≥4.1MPa (ASTM D4541)
